What's with the cookies?
Early on, Jack goes into a conference with the FBI and a plate of cookies. They're from Janie Cates, who's sis was murdered. "Anybody want a cookie?" No one does. He tries foisting. A guy takes one, but doesn't eat it. "Milk, anyone?" No one wants milk. Jack has the "milk maid" bring three glasses. They might change their minds. No one does.
At one point it seems like maybe Jack is chewing. But we never see him actually eat a cookie.
And the point of all this was . . . what, exactly? A red herring, to make us wonder if the cookies were poisoned? Why was Jack so invested in having everyone eat cookies?
If the former, pretty lousy writing. There's no poison I know of that takes exactly 88 minutes to work, and then kills instantly.
